Serious Sam 3: BFE

hi,we want to play coop (2 players) but every few seconds the ping jumps up to 999.we have both a 50 Mbit connection.we already turned of firewall and antivirusthe ping is normal if we join a server from the serverlist.

How far apart do you two live? I only get that when trying to play with people halfway across the world. You may need to play on servers that are in between the both of you so the ping rate is lower. You both could have 100mb connections and have no effect on improving ping rates. Bandwidth has nothing to do with it. Turn on your firewall and antivirus since it has nothing to do with it.
